KIEKERT MULTIPARTITE SLIDING DOOR Filed Aug. 6, 1932 PatentedApr. 9, 1935 Il "PAT-ENTI f op Friederich `Wilhelm Kiekert, Heiligenhaus, Y Germany p 1 Application August c, 1932; serial No. 627,733 'In Germany April 4, 1932 o i f f4 claims.'v (o1. .gu-19) I This invention relates tosliding doors consist-I ing of several parts displaceable in relation tov one another.V The method of construction hither-l to employed for such doors, in which the door parts are disposed adjacent one'another andare displaceable over one another, has-the disadvantage that there is produced a very'wide total crossesection of the slidingdoor and of the door.v

pocket. Furthermore when such doors are closed there is produced at the point of transition from the one door part to the other an unsightly pro-` jection and also a gaping opening at the entry to u the door pocket. I I o According to the invention lthese disadvantages are avoided in that vone orimore of the displace#` Y another. The telescoped door partsarenot much thicker than the single part hitherto employedVV so that the sliding door assembly as a wholeonly Y requires very little space." Unsightly'large steps from the one to the other door' part are avoided and furthermore when the doors Aare drawn out there are no longer any gaps at the entry to the door pocket because the width of the pocket opening corresponds to the thickness of the hollow door. Y I

One constructional form of the door according Vto the invention is illustrated by way of example in the accompanying drawings.

Fig'. 1 is an elevation and Figs. 2 and'3 are cross-sections with in different positions. I .Y I o Figs. l and5V are representations ofthe horizontal sections to a'larger scale and i Figs. 6 and scale.I Io

In the construction illustrated the door halves the parts I and 2 `consist of pressed4 and proliled sheet metal plate. Of course the narrower `part I could however be produced from wood. The part 2 has I an open U-shape in horizontal section which is closed at the one narrow edge Sand is open atV is in the closed position. The doors I and 2 are.

guided vwith respect to one another by? means of sliding guide members Y9, I engaging in one another in a clamp-like manner, the'walls of the door'part Zbeng at the same timefheld together 7 are vertical sections to a larger,

thereby'.` 1 The `door part 2 is suspended by means of rollers VI I,` I2 from ya fixed guide rail I3 of the frame `Ill while the door part I I is suspended by means of a roller I from a guide rail I6 in the `interior of thefdoor part 2 and `bymeans of a roller I'.' mounted on its outer `edge also from the guide rail I3 of the frame. Instead of the rolling vguide rail there may also be provided ball guide l members.y The toothed gear drive i8, I9, 20 for` producing the commondisplacement of the door parts `I `and'2 is constructed in the manner usual i Y for multi-'partite sliding doors.

The drawings show a double sliding door the `parts I of which abut together -for example by re- 1 silient strips 2 I.. InoFigs'. 1, 2 and 4 the doors are shown closed. Y Figs. 3 and 5 show the door part I 'Within'.the door part` 2 and both parts I and 2 slid backtogether into the doorpocket 4 the rdoor Vhas been opened.

Of course, if desired, more than two telescoping door parts may-be provided; I

Iclaim: vv II I 1. A sliding door comprising a hollow outer section consisting of pressed sheetimetal plates arranged in parallel spaced relation and connected with each other only along one vertical edge by whereby i, I

bending saidY plates inwardly, said plates being adapted to telescopically fit into said outer section and consisting of pressed sheet metal plates arranged in spaced parallel relation and connected bending" said Vplates inwardly,Y and interengaging guide members located -respectively oncontigu'- l ous faces `of said door sections slidable relatively `to each otherk with said sections and adapted to `maintain the latteragainst relative spreading in n all positionsoffsaid sections. I 1 I 2. A slidingpdoor comprising an outer section of horizontal U-shape, an inner section tele` otherwise `free from each other, an inner section witheach other along both vertical `edges by I' scopically combined with said outersection, guide with the guide members of said outer section for maintaining said sectionsagainst relative spreading in all positions thereof. r

3. A sliding Vdoor comprising a hollow outer section having aV transverse wall along one vertio cal edge and vbeing open along the other vertical edge, aninner 4door `section telescopically com-v bined withv said outer section, and interengagingl guide members'located respectively on contiguous faces of said door sections slidable relatively' to each other with said sections and adapted to p maintain said outer door section against relativeA spreading inV all positions of said sections.

4.' A sliding door comprising avpluralty of telescopically combined sections slidably displaceable relatively to each other, at least one of said sections beingof horizontal VU-shape, guide members the latter is maintained against relative spreading in all positions of said sections.V
